Also, if you are using BP 1.7 get the development version of GenesisConnect. Someone had reported an issue that I could not reproduce so I’m waiting on followup before releasing the version for BP 1.7.

Everything is working fine without GC except sidebars. So in order to use Genesis Simple Sidebars I have to use GC?

Yes. There isn’t anything we can do in Simple sidebars to make it work with the BP templates/theme compatibility. In terms of the issue you have above the BP templates/theme compatibility is coded to only show the primary sidebar (in any theme).
